In order to be analogous to I0 though wouldn't it need to trim both
leading and trailing spaces? I don't think that would be the usual
desire though, but maybe you could specify '0a0' to trim leading and
trailing spaces.

I don't there such a pressing need - I0 only removes leading spaces
(there are no trailing ones). A0 would only trim trailing spaces (can
use ADJUSTL in the unusual case of wanting to trim leading ones as
well).

I admit it would be a minor inconsistency in the language, but not
unlike the need to use 123_kind for an integer constant, but
kind_"string" for a character constant. People seem to cope with that.

If you're going to the trouble to introduce a trailing space trim
edit, I see no reason not to introduce a similar leading space trim
edit. I agree that it would be needed less frequently, but that's no
reason not to add it when it would be so easy to do so and provide a
more complete solution.
